The release notes for version 8.5.20 indicate that there are updated libraries (Bootstrap, jQuery UI, phpseclib, etc.) Can anyone tell me what versions of bootstrap and jquery UI are used in 8.5.20? I am about to do an update and would like to know if there are additional dependencies I need to check.
Thank you.

If you dowwnload the archive for 8.5.20, you should be able to inspect the various files to see what version they are.

For anyone else – the Jquery is 1.12.2 . There is no version info in the bootstrap files. the jquery was more my concern. Thanks for your help.
